Answer 1

Given info : sunil gave 30% of the total money to his sister. he then gave 25 % of the remaining amount to his brother. He then donated 20% of the remaining amount to a trust and now he's left wealth rs 7308.

To find : the initial money he had, is ...

solution : let Sunil had total amount of money x

case 1 : remaining = x - 30 % of x = 7x/10

case 2 : remaining = 7x - 25 % of 7x/10 = 21x/40

case 3 : remaining = 21x/40 - 20 % of 21x/40 = 84x/200

so, finally he had 84x/200 money left and that is equal to 7308.

so, 84x/200 = 7308

⇒x = 7308 × 200/84 = 17400

Therefore Initial money Sunil had 17400 Rs.
